4 Steps to Test Your Aerosol Valve Performance

A reliable aerosol valve can make or break a product. From spray feel to storage safety, あらゆる細部が重要です. If you’re working with an aerosol can valve, バルブアクチュエーター, or full aerosol dispensing system, these checks keep performance tight and consistent. 実践的に分解してみましょう.

ステップ 1: Verify Assembly Tolerance and Crimping Specifications

When testing an aerosol valve, start with how parts fit together. Poor assembly tolerance or off-spec crimping specifications often cause leaks before the product even leaves the line.

• Inspect core valve components
• Measure actuator fit
• Confirm can interface alignment

それからさらに深く進んでください:

1. Check mounting cup dimensions
2. Evaluate gasket material compression
3. Measure crimp diameter and depth

Look closely at:

• ◎ Uniform curl under the cup
• ◎ No distortion at the sealing edge

If the mounting cup and gasket don’t seal cleanly, pressure loss happens fast. A well-built aerosol dispensing valve should sit tight without crushing internal parts. で ファンシュン, tight tolerance control keeps deformation low and repeatability high.

ステップ 2: Measure Spray Rate and Flow Characteristics

Spray performance tells you how the aerosol valve behaves in real life. Users notice it instantly.

主要なチェックには以下が含まれます:

• Spray rate stability
• Discharge rate under different propellant type
• Required actuation force

Flow depends on:

1. ノズル設計
2. Orifice size
3. 製品粘度

ショートバースト. Long holds. 上下を逆にして使用する. Test them all.

If flow feels uneven, adjust nozzle geometry or match the valve better to formulation thickness.

ステップ 3: Assess Leakage Rate and Pressure Rating

Pressure testing protects both brand and user. A single weak gasket seal can ruin storage stability.

Pressure Testing Reference Table

テスト項目	目標値	試験圧力 (バー)	間隔 (時間)
漏れ率	≤0.3% wt	6	24
Pressure rating	No burst	12	1
シールの完全性	No bubbles	8	0.5

Process logic:

• Fill can
  • Pressurize to rated can pressure
    • Submerge and observe
    • Record mass change

Strong valve integrity ensures compatibility with hydrocarbons or compressed gas systems.

ステップ 4: Analyze Particle Size Distribution and Quality Control

Spray feel comes down to particle size distribution. Too coarse, and coverage suffers. Too fine, and drift increases.

焦点を当てる:

• Droplet size range
• Spray pattern symmetry
• Atomization efficiency

規制された市場向け:

1. Validate formulation consistency
2. Monitor spray uniformity every 2 時間
3. Document quality control metrics

Pharma and personal care brands expect tight product performance standards. A tuned aerosol valve system delivers smoother application and fewer complaints. That’s why manufacturers working with ファンシュン test beyond basics and treat every aerosol valve like a precision component, not just a small metal part.
